Without having ever (intentionally) used jack (JACK (Jack Audio Connection Kit)), I would guess that it might be useful. (Like Jeremy says, you will need 3 output devices.) Somewhere along the line I bought some audio devices (my choice of words) that are, afaik, like a sound card built into a very small (USB) plug like device. I can plug it into a USB and then plug stereo headphones into it--the device functions like a sound card, self powered from the USB port. I bought those, as I often do such things, off ebay from the far East. I suppose you might do a hinky workaround to get two output devices from one (stereo) sound card by (possibly after merging stereo signals into a mono signal) sending a different (mono) signal to each channel (i.e., left and right) of a stereo sound card, at least for a sort of feasibility test. Do they make 5.2 or 7.2 sound cards for computers--if so, you could consider a similar approach using those 5 (or 7) channels.
